[EDIT: Sharkie's later pointed that out. I should read the entire thread. ]

The manufacturer's warranty is then (as always) secondary to Australian consumer law. This part is a bit different to what Sharkie's said - the manufacturer has to prove the association, they can't just look and say "oh, you had a crash, we're just not covering that any more".
Yes, fully agree that they have to prove the association, however ... damage to a component that is not detected at the time OR your cheap insurer won't fix, that may well lead to premature failure of that component will always be assessed under the "reasonableness" rule. As in ... is it reasonable to deny a warranty claim if the failure of said component can with a high likelihood be attributed to the accident. The answer may well be in favour of the manufacturer ....

Now, in this case, luckily all is not lost, as the above finding will then open an avenue to pursue the insurer to actually "redo" the repair and replace the faulty component (that they should have done in the 1st place). The only problem with this is the time that you will be without the car fighting to get it fixed properly.
